Hi Tony.
I've posted a thread on this before.
I have had to do an emergencey stop at speed and there is realy nothing to be too concerned about when doing this in a straight line, but should you be cornering at the time, then you do have to resist temptation just slap the anchors on (brake sharply)and hope for the best.
As an advanced driver, I've learned to be much more aware of the traffic in my surroundings and be antcipative of what they are likely to do. Also having a plan "B" up your sleeve also helps.
Common sense tells us all that braking in a corner causes the car to slide off coarse, but put a caravan/trailer on the back and that inertia effect multiplies ten fold. Anti lock brakes help a lot of people out, but again that is not necessarily the solution to the situation. Having a good quality pair of tyres on the front axle again has a very positive benifit as thye will grip the tarmac better and for longer, giving you a few vital seconds to think and react.
But being observant in the first place is by far the best tool in you box. Looking further ahead when evaluating the road conditions and traffic, coupled with adjusting you driving to a more steady level, will all avoid the situation before it happens.
Now add plan "B" to the equasion. Look for alternative escape routes should you not be able to stop in time, rather than wait for the bang! Grass verge comes to mind, or even as a last resort use the opposite sideof the road, but only do that if you can CATAGORICALLY SE NO ONCOMING TRAFFIC ! You must not risk the lives of others to save your own skin, after all if you are driving sensibly in the first place you will not need to perform an emergencey stop.
I'm no slow poke on the roads by any means, but I get around 35'000 miles to a set of front brake pads and triple that on the rear pads. I usually go well past 100'000 miles on a clutch too.
What I will say though is find an empty large carpark and have a go at emergency stopping so that you get a preview of what happens. Don't get too adventurous with stopping while cornering, do that one slowly at first and you will soon find out how un-nerving that manouver can be.
